Initial Startup
After the melter has been properly installed, initial startup can take place.
Purging Melter
The melter was subjected to extensive testing prior to shipment. In doing so,
the tank was filled with a special test material. Material residue may still be
present in the melter. To remove the residue, melt and feed several
kilograms of material before starting production.
1. Ensure that inert gas is connected.
CAUTION: Do not operate Nordson gear pumps without material. Before
switching on the motor, ensure that the tank is filled.
2. Fill the tank (Refer to Filling the Tank).
3. Set the main switch to I/ON.
Position I/ON = Melter switched on.
Position 0/OFF = Melter switched off.
Padlocks can be used to protect the main switch from being turned on by
unauthorized personnel.
The melter tests the LEDs of the component and function keys on the
control panel and begins heatup (LED on Heater key turns green).
NOTE: The LED test allows the operator to check that the LEDs are
working properly. There is no error indication in the event of a faulty LED.
Refer to section Repair, Replacing Control Panel (Service Kit).
The tank is pressurized with inert gas according to the time set.
4. Set the setpoint temperatures (Refer to Adjusting Setpoint
Temperatures).
Comply with the processing temperature prescribed by the material
manufacturer.
